ABSTRACT:
A bushing base plate comprised of a bushing base raw plate containing a circular or irregular aperture having inner surfaces and inner diameters; and a hollow tube having outer surfaces and out diameters which is inserted into the aperture and bonded thereto by thermal diffusion. Prior to insertion of the tube in the aperture, the outer diameters are greater than the inner diameters, thereby producing a pressing force between the outer surfaces of the tube and the inner surfaces of the aperture.
